CARL L. KOSTER AND FREDERICK J. DAVIS, OF'SAN FRANCISCO, AND JULIUS J. KBOHN, OF ARCATA, CALIFORNIA.

= RECORDING DEVICE.

To all whom it may concern:

Be it known that we, CARL L. KosTER, FREDERICK J. DAVIS, and JULIUs J. KnoHN, citizens of the United States, the said CARL L. KOSTER and FREDERICK J. DAVIS residing in the city and county of San Francisco, State of California, and the said JULIUs J. KRoHN at Arcata, county of Humboldt, State of California, have invented certain new and useful Improvements in Recording Devices, of which the following is a specification.

The present invention relates to an instrument primarily designed for use in logging camps or other places where cable hauling is employed, to record the travel of the cable on each trip thereof, the time required to make each trip, and to determine the efficiencyof the crew operating with each cable. 1

The invention has for its principal objects to provide an apparatus whereby a record is made as to the distance traveledby the hauling cable during each trip thereof so,

that the life and record of the travel of the cable will be provided; to provide an apparatus which will record the interval of time required in making each trip of the cable, whereby an accurate record of the operation of any given crew working in connection with the cable may be had; one whereby the operator of the cable controlling means may readily ascertain at all times the length of cable unwound from the drum.

With the above mentioned and other objects in view, the invention consistsin the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings-and pointed out in the claims hereto appended; it'being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, 1

Fig. 8 is a View in side elevation of the mechanism cooperating with the towing cable or back line and which operates the chart holding drum. Fig. 9 is a vertical sectional view taken on line 99, of Fig. 8, showing more fully the tension device for the grooved pulleys. Fig. 10 is a top plan view of the mechanism disclosed in Figs. 8. and 9 illustrating more fully the arrangement of the connecting links. Fig. 11 is a view in detail of the mechanism for resetting the recording-device. Fig. 12 is a view in detail of gm operating shafts taken on line 1212 of While the device is disclosed as being operated by the back line cable, it is to be understood that the same may be equally as well applied to operate in connection with the towing or pulling cable, or, in fact, may be employed in connection with any cable or member which is extended for various lengths and relative to which a record of the travel thereof is desired to be obtained.

Referring more particularly to the several views of the drawings, wherein like characters of reference designate corre sponding parts throughout the several views, 1 indicates a suitable main or towing cable of a logging equipment to one end of which is attached the back line 2 preferably of lighter material. The lines 1 and 2 operate around a suitable sheave 3 and are to any suitable winding'mechanism. p

The back line 2 operates between the rotatable sheaves 4 and 5 respectively carried by shafts 6 and 7, supported by the stirrup 8, preferably suspended from a hanger 9, which provides a flexible support therefor.

The shaft 6 extends through vertical slots in the stirrup .and through openings in a guide 10 slidably mounted in the stirrup 8, and the guide 10 is forced downwardly by the coiled spring 11 received at its opposite ends in cups 11 carried respectively by the stirrup and guide, and said spring is maintained under tension by the adjustable screw 12 passing through the top of the stirrup. Suitable, guide or steadying rollers 13 between which the line 2 passes are connected by the members 13 and are arranged in pairs, one on each side of the sheaves 4 and 5, and said members 13 are connected to the main shafts 6 and 7 by the pivoted links 14, certain of which are formed at their ends in bearings in which the shafts 6 and 7 operate. The guide or steadying rollers guide the line 2 in passing between the sheaves 4 and 5 and prevent the line from passing therebetween at an angle.

A flexible shaft 15 is mounted to rotate with and extends from one end of the shaft 6 and said shaft connects at its opposite end with one end of a shaft 16 rotatably mounted in a suitable housing 16 and supported by bearings 17. The shaft 16 carries a suitable pinion 18 which intermeshes with a suitable gear 19 carried by a shaft 19 rotatably mounted in bearings 19 The shaft 19 carries a worm gear 19 which intermeshes with a suitable gear 19 formed on the lower peripheral edge of a vertically disposed rotatable drum or cylinder 20 through which extends the opposite ends of a shaft 21 which rotates in suitable bearings 22. The upper end of the shaft 21 extends through the top of the housing and carries an indicator hand 23 which is adapted to cooperate with a dial 24 having graduations thereon indicative of lineal feet, said dial and indicator hand being protected by a suitable transparent covering 25.

The drum or cylinder 20 is provided on its outer surface with a vertically disposed row'of studs 26 which are adapted to project through suitable a ertures in opposite side edges of a suita ly ruled chart 27 adapted to be wrapped about the cylinder or drum. The chart 27 is maintained in position by a suitable vertically disposed .bar 28 hinged at its lower end, as at 29, to the lower portion of the cylinder 20, and provided within its length with pins3O which are adapted to extend into the apertures 32 formed on the face of the cylinder or drum, and which are adapted to be forced through the chart 27 when the bar 28 is forced thereagainst. The free end of the bar 28 is adapted to cooperate with a spring.

catch. 33 carried by the upper end of the cylinder or drum 20 and is retained in locked position against the outer face of the chart thereby. The chart 27 is provided on its upper edge with graduations 27' indicative of lineal feet, and is ruled horizontally and each horizontal line is numbered indicative of the hours of the day, including a period preferably from six in the morning until six at nlght. Vertical rulings on the chart cooperate with the graduations 27 on the upper portion thereof.

A suitable marking device 34 cooperates with the chart 27 and the same is yieldably mounted in a support 35 and is maintained in contact with the shart by a spring 36. The support 35 is formed with a threaded bore through which extends the threaded shaft 37 rotatably supported at its lower end by a frame 37', and at its upper end in a bearing 38, and the rotation of the shaft causes the marking device to move vertically relatively to the chart and provide indications thereon. A guide 39 secured at its ends extends through the marker support 35 and provides a means for preventing the rotation of the support and for maintaining the marker in cooperation with the chart. A beveled pinion 40 is carried by the lower end of the shaft 37 and cooperates with a gear 41 carried by a shaft 42 rotatabl mounted in the frame 37 and said sha 42 carries on one end an operatin handle 43 and cooperates at its other en through the ratchets 44 and 44 retained in engagement by the spring 44 with a shaft 45 associated with the hour hand of a suitable clock or other time controlled mechanism 46. The time controlled mechanism is mounted in the side of the housing 16 and the hands and dial thereof are visible through a transparent covering 47. The housing is also provided with a transparent panel 48 through which the chart and marking device are visible.

It will be apparent that the operation of the clock mechanism 46 will cause the shaft 37 to rotate and which rotation will draw the marking device downwardly on the chart 27. The passing of the back line 2 between the sheaves 4 and 5 will cause the same to rotate, first in one direction and then in a reverse direction, and this motion will be.

or drum 20 and cause the same to oscillate,

and the time controlled markin device cooperating with the chart carrie by the os cillating drum or cylinder will provide a record of each movement of the cable, a record will also be maintained as to the length of cable unwound from the wlndmg drum and of the time required for the travel of the cable in either direction.

The eriod of time that the drum remains idle Wlll also be recorded as the marking device then asses thereover in a straight line. When 1t is desired to reset the marking device to its uppermost posit on to co operate with the chart at the beginning of a working day, it is only necessary to grasp the handle 43 and rotate the same in a counter clockwise direction, which will permit the ratchets 44 and 44' to override each other and cause the support to be elevated to the upper portion of the shaft 37 A pinion 49 is carried on the shaft 16 and intcrmeshes with a gear 50 mounted to rotate with a shaft 51 and said gear carries at one side a pivotally mounted spring pressed pawl 52 which cotiperates with a ratchet 53 loosely mounted on the shaft 51, and causes the ratchet to rotate in. one direction. The ratchet is prevented from rotating in a reverse direction by a retaining spring 54 which is mounted on the base of the cabinet, and which cooperates with the teeth of the ratchet.

An arm 55 is carried by the ratchet 53 and the same on each rotation of the ratchet cooperates withthe operating wheel 56 of an odometer 57, of any well known type. The cabinet is divided vertically on the line 58 and the sections are hinged, as at 59, to permit access to the interior of the cabinet when it is desired to change the chart, renew or refill the marking device or reset the marking device or Wind the clock.

It will be apparent that a structure has been provided wherein the chart after being used iscapable of being readily replaced, one wherein the chart is operated relative to the marking device in accordance to the direction and length of travel of the operating cable. By the improved device a chart is maintained as to the daily operation of the cable and by doubling the registration of the odometer, the total travel of the cable may be obtained.

The apparatus is so constructed that the gear relation between the sheave 4 and the drum or cylinder 20 is such that the vertical graduations on the chart carried by the drum or cylinder bear a fixed relation to the circumference of the sheave 4 and the movement of the marking device and the horizontal graduations on the chart bear a fixed relation to the operation of the time piece, which construction insures a correct operation of the apparatus under all conditions and at all times.
